This place contains a mine, dangerous ash beasts, another forge and an awesome object too cool to spoil here! Note: Ash beasts are extremely dangerous creatures who do not want to be disturbed.
Also this place leads to Mount Fisty, the Everest of the Hellmoo world.
More to be added as I think of it.
A reminder, as a mine, you'll need some light. Unlike the normie mine here in hell, this one contains heat, so you're either going in with light clothes or with solar sponge.
Best mining place ever.
